LG Display just unveiled the largest flexible transparent OLED display measuring 77, it can be used on store fronts, smart desks and various augmented reality tasks. While a 77 slab would hardly be portable, this display can be rolled up to a radius of 80mm (just over 3).
It has a transparency of 40% and a proper UHD resolution (3,840 x 2,160px). Curvy, transparent screens struggled for resolution in the early days, but LG has been at this for 5 years (after it beat Samsung Display in 2012 for a government grant).
Things have progressed quickly over that time in 2014, it showed off a small 18 version (1,200 x 810px resolution), then in 2016 LG brought that up to 55. Last year, the company demoed some truly bonkers displays – an S-shaped OLED, 139″ in size and 8K in resolution, and a double-sided 55″ display.
